| Abstract: | In this paper,polyelectrolytes PMAA-NH4 was used as dispersant. The rheological properties of Ba-TiO3 suspensions and the effect of dispersant concentration and pH value on suspension stability were studied by means of zeta potential measurements (Sedimentation experiments, viscosity measurements and particle-size analysis etc. At last,the stabilized and dispersed suspension was prepared at the best pH value ( = 9. 0)and dispersant concentration. So a new way for preparing BaTiO3 ceramic concentrated suspension with a low viscosity in alkaline condition was abtained. 4figs. ,11refs. |
